Transcript for Katrina Survivor 10 Years On
We want to head to new Orleans now, on the eve of a solemn anniversary. Ten years ago, hurricane Katrina hit. The city underwater, residents stranded. The cry for help on that roof. The superdome, families huddled inside. And bob woodruff was there ten years ago, and tonight he's back. Bearing witness to one city's strength, and one survivor's journey back. Reporter: Ten years ago, the worst about to come. The next morning, the water bursting through the levees, first burying the ninth ward. This was then. Today, New Orleans is back. Ten years ago, the convention center, surrounded by desperation. Now, the economy is booming. Katrina is considered the single most catastrophic natural disaster in U.S. History. More than 1,800 dead. I never forgot this 10-year-old girl I met. Are you getting water and food? I'm not drinking that water. Reporter: Fled with her mother to Houston, and never returned. This week, we found her. Can you believe we traced you down? After living through foster care and family tragedies, now she's thriving. Planning to become a minister. I can help so many other people in ways that others can't, because of what I had to go through, experience, and overcome. Reporter: Tomorrow, there will be mourning for those that were lost, and a huge parade that ends in a street party.
